How Much Does a Mobile App Really Cost in 2026?

Quotes from €10k to €250k for "the same" app are not random. What really drives the price, the realistic ranges for 2026, and where cutting costs backfires.

Why Quotes Differ So Wildly

Send the same brief to five vendors and you'll get quotes from €10k to €250k. That doesn't mean someone is lying. It means each of them priced a different app, because the brief left too much unsaid.

I build mobile apps end-to-end: architecture, backend, release to the App Store and Google Play. Below is what I actually weigh when pricing a project, so you know what to ask before signing anything.

What Actually Drives the Price

Counterintuitively, the number of screens matters little. A screen is hours of work. The price is made by architectural decisions:

• Backend. An app that keeps everything on the device and an app with user accounts, sync and an admin panel are two different projects. The backend can cost more than the app itself.
• Integrations. Payments, maps, calendars, your internal systems. Each integration isn't just "wiring an API", it's handling every way it can fail.
• User roles. One type of user versus customer + provider + admin multiplies the flows to design and test.
• AI and data processing. Features built on LLMs or computer vision add infrastructure cost and a separate quality-tuning loop. I wrote more in my piece on AI in mobile apps.
• Offline mode. "It should work without internet" sounds like a feature but is an architectural decision touching every layer of the app.

Realistic Ranges in 2026

The ranges I see in the market, assuming one codebase for iOS and Android (Flutter):

• A simple MVP without a backend (local logic, a handful of screens, store release): €10–22k with an independent developer, from ~€40k at an agency.
• A product with a backend and accounts (sign-up, sync, notifications, payments): €22–50k with an independent developer, €60–150k at an agency.
• A product with AI / custom architecture: priced individually; the floor for credible offers is around €35k.

Why such a gap between a solo developer and an agency? An agency bills you for a project manager, a salesperson and an office. An independent developer working with AI agents now ships a scope that three years ago required a small team, and does it without that overhead. It's not the right fit for everything: at very large scale or under heavy compliance requirements, a team makes sense.

Hidden Costs Nobody Mentions in the Quote

• Backend running costs: from a few euros to a few thousand per month depending on architecture. Ask about this before the stack is chosen.
• Developer accounts: Apple ($99/year) and Google ($25 one-off), plus yearly certificate churn.
• OS updates: every new iOS and Android release breaks something. An unmaintained app ages faster than you'd think.
• Store review: a rejected release is a week of delay. An experienced developer knows the usual rejection reasons and avoids them upfront.

Where to Cut Costs Smartly

• One codebase for both platforms. Flutter instead of two native apps is nearly half the budget for 95% of use cases.
• A managed backend instead of a custom one. Supabase or Firebase compress months of work into weeks. A bespoke backend makes sense only once the product demands it.
• An MVP scoped to a hypothesis, not a vision. Build what tests the business model. Everything else can wait for 1.1.

And where not to cut: analytics and crash reporting (without them you're blind after launch), the release pipeline, basic onboarding. Skimping there is the most expensive saving you can make, the bill just arrives after launch.

How to Get a Quote That Means Something

Instead of a feature list, send the developer three things: who will use the app, what problem it solves, and how you'll know it's working. A good quote starts with that conversation, not with a price per screen.
